We, who think like animals living in small groups, must structure a global world. We believe in universal human rights and believe racism and war are wrong. On the other hand, it is our nature to be cooperative and loving almost exclusively with the members of the group to which we feel we belong.

Popular culture bombards us with examples of animals being humanized for all sorts of purposes, ranging from education to entertainment to satire to propaganda. Walt Disney, for example, made us forget that Mickey is a mouse, and Donald a duck. George Orwell laid a cover of human societal ills over a population of livestock.

If you ask anyone, what is morality based on? These are the two factors that always come out: One is reciprocity, … a sense of fairness, and the other one is empathy and compassion.

Morality, after all, has nothing to do with selflessness. On the contrary, self-interest is precisely the basis of the categorical imperative.

The chimpanzees could tear me apart in no time. They're many times stronger than we are.

Human morality is unthinkable without empathy.

You should know as much as you can about the human species if you have a hand in designing human society. Of course, I'm not saying that you can derive moral rules from nature - that's deriving an ought from an is, as the philosophers say - but you do need to know what kind of animals we are if you want to design a stable society.
